Nasal Cavity Metastasis From Colorectal Cancer Represents End-Stage Disease and Should Be Palliated

Nasal metastases from colorectal cancer is rare. The presentation of nasal metastases is often very similar to primary nasal sinus adenocarcinoma. A high index of suspicion is required, especially in patients who have had a previous history of colorectal carcinoma. Histology is ultimately required for diagnosis. We describe 2 cases of nasal metastases from colorectal carcinoma, and discuss the presentation, diagnosis and management of the case. Such metastatic disease ultimately represents end-stage malignancy, and patients should be palliated.

Cystic lymphoid hyperplasia of the parotid gland as the initial manifestation of HIV infection

We report the case of a patient who presented with cystic lymphoid hyperplasia of the right parotid gland as the index diagnosis of HIV infection. Histological examination of the excised parotid gland revealed a solid-cystic lymphoepithelial lesion with a non-keratinous squamous epithelium, which grew into the lymphoid component via anastomosing cords and islands. These anastomosing cords and islands contained variably abundant B cells, several subepithelial multinucleated histiocytes, salivary ducts infiltrated by small lymphocytes, and a dense lymphoid infiltrate containing lymphoid follicles with enlarged, irregular germinal centres.
